Title: Apparatus for controlling web edge perforation pitch
IPC: B26D7/01
Filed: 1966-02-09
Abstract: 1,138,586. Automatic spacing control. MASCHINENFABRIK GOEBEL G. m. b. H. ' Feb. 9, 1966 [Feb. 11, 1965], No. 5742/66. Heading G3R. The pitch of perforations being made at the edge of a moving web is maintained constant by controlling the speed of the web from two photoelectric heads, one responsive to rotation of the perforator, and the other, located at a multiple of the perforation pitch in the direction of travel of the web, being responsive to the passage of the perforations. As described, a paper web leaving a printing machine passes a rotary edge perforator on its way to feed-out rolls. A photoelectric scanner associated with the rotary perforator produces a pulse once per revolution of the perforator and the timing of this pulse is compared with one produced by another photoelectric scanner viewing the perforations some distance downstream of the perforator. Lack of synchronism, indicating change in hole spacing, produces a current which causes a motor to correct the spacing by adjustment of a variable speed gear in the drive to the feed-out rolls. A switch, operated during a limited portion of the rotation of the perforator near the synchronizing point renders the photo-electric scanner viewing the perforations ineffective during the remainder of the revolution. The last-mentioned scanner is adjustable longitudinally relative to the web by a manually operated screw to facilitate initial setting of the desired spacing after a trial run.

Title: Improvements in or relating to reclining chairs
IPC: A47C17/16
Filed: 1954-02-26
Abstract: 758,952. Reclining chairs convertible into beds. MAURER, P. Feb. 26, 1954 [March 6, 1953], No. 5802/54. Class 52(2). Relates to a chair of the kind having interconnected back, seat and leg-rest so suspended from the chair frame that the lying back of an occupant causes pivoting of the back downwards, raising of the seat and projection of the leg rest. The invention resides in the suspending and interconnecting linkage described below, which is so constructed that the supporting surfaces of the parts can be brought to lie in the same horizontal plane. There are two similar linkages, one at each side, and each comprises a first bar 55 secured to the chair frame. A second bar 56 carries the seat 53 and is suspended from bar 55 in a sloping manner by a long rear link 57 and a short front link 58. The latter is extended downwardly at 71 and, together with a link 75 suspends a third bar 73 from the second bar 56, bars 56, 73 being always parallel. Third bar 73 has a post 77, braced by a strut 78, and an arm 79 fixed to the leg-rest 54 is pivoted at 80 to the top of the post. Second bar 56 carries a fixed post 66 to the top of which is pivoted an arm 63 fixed to the back 52. A supporting link 64 for the back is pivoted to the arm 63 and the first bar 55. In operation, as the occupant leans back, the back pivots rearwardly and post 66 pulls up the second bar 56 so that the seat 53 is swung forwardly and upwardly to the position of Fig. 4. Because rear link 57 is longer than front link 58 the back of the seat is raised more than the front and the seating surface becomes horizontal and co-planar with the back. Meanwhile front link 58, through its extension 71 lifts the third bar 73 to raise the leg-rest which is swung to horizontal position by a link 83 joining bar 79 to link 71. A stop 28. on first bar 55 limits the upward movement of link 57 to define the lying position and limits the downward and rearward movement of post 66 to define the sitting position.
